The loudest noise or sound is The Bloop because in 1997, U.S. NOAA heard a sound that is never been heard of that is also the loudest sound ever. The sound can cause from more than 5,000 km away from it's source. If it is an animal, it is louder and bigger than the loudest animal and the biggest animal in Earth.
The explosion from the Krakatoa volcano in Indonesia is the loudest sound ever to be heard. It could be heard from over 3,000 miles away.
the first sound which is the "lupp" sound is loudest and longer.
